Feisol is great! Only gripe is the ballhead is way too beefy for my application. It weighs more than the legs, and is able to hold weight far beyond what I need. I'm thinking of getting a manfrotto compact ballhead to replace it.
With the lenses I currently have, I'll never need that much support =(
Otherwise it's an awesome setup. Ball head is easy and accurate to use, legs are very light and sturdy. I can lean up against the tripod when taking pictures, showing really how much weight it can really stand.
